Embodiment 1

[0017] Select all cotton cloth or composite fiber knitted fabric, fluorescent dyes as dyes, including the following steps:

[0018] (1) Pre-treatment of the fabric, put the fabric into the cleaning solution with detergent, configure 1-2g / L detergent according to the bath ratio of 1:50-60, put the fabric into it, and wash it in the greenhouse , dry;

[0019] (2), remove enzyme, carry out enzyme removal by the fabric after pretreatment in described step (1);

[0020] (3), cationic modification and dyeing process, remove the plush and hairiness on the fabric by removing enzymes in the step (2), put the fabric into the dye liquor after washing, and carry out cationic modification and dyeing successively , according to the following parameters to prepare the cationic modified liquid: if the amount of dye is 1%-10% of the cloth weight, the weight of the modifier added is 2%-6% of the cloth weight, and the softener is 0.5-1g / L; If the amount of dye exceeds 10% of the cloth weight, ...

Embodiment 2

[0024] Use rayon or cotton viscose, except that the highest temperature is 60°C during cationic modification and fluorescent dyeing, and the rest of the operating steps and preferred schemes are the same as in Example 1.

[0025] Matters needing attention during actual operation: Due to the difference between large and small samples, the present invention is a technical solution for small samples. When making large products, the amount of dye needs to be added to the small sample by 10-15%; attention should be paid to modification and There should be no foam during the dyeing process. If there is foam, add defoamer in time to keep the whole process free of foam; after modification, it must be cleaned to prevent unreacted modifier from remaining; The hairiness is cleaned; the minimum dosage of modifier is 2% of the cloth weight, and the maximum dosage is 8% of the cloth weight.

[0026] The present invention adopts the above-mentioned technical scheme to provide a processing me...

Abstract

The invention relates to a processing method based on dyeing on composite type fiber fabric. The method includes the steps of conducting pretreatment, dezymotizing, modification, dyeing, overflow washing, water drainage and the like on the fabric. The defects of non-ideal dyeing effects such as dyeing defects which easily occur in the traditional technology are overcome by controlling the temperature, the time and the PH value, fluorescent paint dyeing is conducted through overflow dyeing, the even dyeing property of the cloth cover is good, and the application range is wide; modified treatment is conducted on the gray fabric through positive ion modifiers, and the modified gray cloth can still have high whiteness, strong force and good moisture absorption performance.

Description

technical field [0001] The invention specifically relates to a processing method based on dyeing on composite fiber fabrics. Background technique [0002] Because dyeing dyes are easy to color when they are dyed in the overflow machine, the color error is large. At present, most dyeing factories have failed to develop fluorescent dye overflow machines for dyeing, and most of the traditional dyes use heavy metal salts, which not only pollute the environment, but also cause shade. Difficult to control stably, not suitable for mass production. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a processing method based on composite fiber fabric dyeing, by controlling temperature, time, and pH value, it overcomes the defects of unsatisfactory dyeing effects such as easy coloring in the traditional technology, and the coloring effect is good. No staining, good level dyeing of the cloth surface, the modified fabric still...
